Abstract

PURPOSE: To enable magnification to be changed easily even in the case of a camera using a film of a particularly small image size by moving the taking lens along the taking optical axis.
CONSTITUTION: The 1st opening 16 for macrophotography and the 2nd opening 17 for standard photography are provided to the front of a camera body. In the case of macrophotography, the light from a subject 1 is led via a reflecting mirror 3 to a lens 4 and is further imaged into a film plane 7 via a half mirror 6. The image 1a at the macrophotography is observed with a convex lens 8. In addition, the 2nd opening 17 is closed by a shading plate 15 and a standard lens 14 is out of the optical axis. Here, the shutter is shown by 10. The change of magnification is accomplished by moving the lens box including the lens 4 etc. At the standard photography, the opening 17 is opened and the opening 16 is closed by moving the shading plate 15 and the standard lens 14 is put on the optical axis. A flash light source 9 is used depending upon the rates of magnification.
